plasmas the fourth state of matter

. Molecules are always in motion. When molecules interact, they rebound elastically and without energy loss. Words to Remember : Brownian motion; Diffusion; Kinetic theory of matter; Plasma; Viscosity; Melting point; Boiling poin..

Properties of Matter - A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystallin..

Summary Matter is anything that occupies space and has mass Element is a pure substance, which can neither be decomposed nor built from simpler substances by any physical or chemical means. It contains only one kind of atom. Broadly speaking, elements can be divided into metals..

States of Matter - All matter consists of atoms and molecules. Each of these atoms and molecules has certain amount of energy. The level of this energy decides the state in which the matter exists. When heat energy is supplied to matter, t..

According to the dynamic particle model all states of matter are made up of tiny particles and matter as a result is an aggregation of very small particle..

Pressure has little effect on the state of solids and liquids as the inter-particle distance is already minimized in these situations. However, the effect of pressure in case of gases is considerabl..

This theory explains the physical properties of matter in terms of motion of its molecules. According to this theory, every substance (solid, liquid or gas) consists of a large number of minute particles called molecules. A molecule may be defined as the smallest particle of a subst..

Kinetic Theory of Matter - This theory explains the physical properties of matter in terms of motion of its molecules. According to this theory, every substance (solid, liquid or gas) consists of a large number of minute particles called molecules . A molecule may be defined as ..

All matter is made up of particles called molecules. In normal circumstances it exists in three states. All the molecules of a given substance are alike in all respects. The molecules are separated from one another by the intermolecular space which is more than the diame..

Is Matter Around us Pure - Summary Matter is anything that occupies space and has mass Element is a pure substance, which can neither be decomposed nor built from simpler substances by any physical or chemical means. It contains only one kind of atom. Broadly speaking, elements ..
